HAND-OPERATED PROPELLING MECHANISM.

Application filed April 30, 1912.

To all lifi/rom t may concern Be it known that SAMUEL WV. REYNOLDS, acitizen of the United States, residing at Scranton, in the county ofLackawanna and State of Pennsylvania, have invented a new and usefulImprovement in Hand-Operated Propelling Mechanism for Boats, of whichthe following is a specification.

The primary object of this invention is to provide a simple andeffective mechanism for propelling boats by hand while the operator is(or operators are) seated either facing the bow or stern and which willutilize as much of the force imparted by the operator (or operators) aspossible in pro- ]jielling a boat either forwardly or backwardly.

In the accompanying drawings forming part of this specification, Figure1 is a side elevation of a boat partly broken away to eX- pose theinterior operating mechanism; Fig. 2 is a plan of a detail portion ofthe boat looking at the operating mechanism; Fig. 3 is a side elevationpartly in section of the ratchet mechanism employedV forA propelling thedrive shaft; Fig. 1 is a longitudinal section of part of the ratchetmechanism, and Fig. 5 is a cross section taken upon the line X-X of Fig.4.

I n the drawings A represents a boat having a propeller 2 of ordinaryconstruction mounted upon a main shaft 3. Said propeller shaft carries afly wheel el. and is journaled in suitable bearings 5 and 6 which aresecured to the hull of the boat. The bearings 5 and 6 have alsojournaled therein a drive shaft 7 lying parallel with the propellershaft and carrying right and left hand threads between the journals 5and 6. This drive shaft is connected at one end to the propeller shaftby gears 8 and 9 which intermesh and are so proportioned in size as toincrease the speed imparted by the drive shaft to the propeller shaft.The drive shaft is driven by means of a clutch 10 which is reciprocatedlongitudinally thereon by means of a rocker arm 11, said rocker armbeing secured to the yoke frame 12 of the clutch by means of aconnecting rod 13. The rocker arm is journaled at its lower end in thesupport 14: which is secured to the hull of the boat and its upper endis provided with a handle 15 by means of which the arm l1 can be swungbackward and for-- ward in the boat while the operator is (orSpecification of Letters Patent.

operators are) seated either facing the bow or the stern as desired.

The connecting rod 13 is pivotally connected between the ends of therocker arm and to the yoke frame 12 of the clutch between a pair ofiianges 16 thereon. The yoke frame is slidably mounted upon thepropeller shaft 8 so as to prevent the clutch from turning as it isreciprocated on the shaft 7. The clutch proper consists of a pair ofcollars 1T and 1S, the one being fitted internally to the right handthreads of the propeller shaft T and th.: other to the left hand threadsof said shaft. Each of these collars has its periphery toothedlongitudinally to form longitudinal grooves 19 in which dogs 2O ani. 21are aoaptedto play and engage. said dogs being held in the body andlying idle in the channel 23 therein. Each of these dogs is formed witha shoulder Q1 for engaging the teeth at the sides of the grooves 19. oneend of each dog being also formed with end shoulders 25 lying in notches26 in the body 22 to limit longitudinal motion ofthe dogs but permittingthe dogs to be tilted out of engagement with the teeth on the collars,the lower surface below the notches 2G in the body 22 being inclined at27 to permit said tilting action of the dogs.

On the outside of the body is a sleere or housing 28 secured by means ofa bolt .29 to said body and lying within this sleeve is a guide plate 30carrying on its lower surface a leaf spring 31, the ends of which slideupon the surface of the dogs, said guide and spring being free to movelongitudinally in the channel i?) over the dogs. Either dog 20 or 21when in engaging position with the clutch is held into engagement withthe same by one end of the spring 31. The upper portion of the guide 30has a lug 32 which is free to move endwise in the longitudinal slot inthe sleeve 9.8. When the guide 30 is moved in one direction by theprojecting lug 32 one end of the spring 31 is adapted to tilt one of thedogs out of engagement with the teeth with which it cooperates on thecollars 17 and 18 and when reversed the other end of the spring 31 tiltsthe other dog out of engagement with its coperating collar, therebycausing motion to be communicated by the clutch to the drive shaft andrevolving the latter in for ward or backward direction according towhich dog is engaged in the clutch. When the spring is in medianposition both of the dogs are held engaged with the two collars 17 and18, the drive shaft within being locked and prevented from revolving ineither direction.

The shoulders 24 on the dogs 20 and 21 are positioned on opposite sidesof the axis of the drive shaft 7 and the collars 17 and 18, so that oneside of the shoulders 24 lies adjacent the side of the channel 23 Whilethe other side engages with one of the teeth formed on the collars 17and 1S. T he width of the shoulders 2d is greater than the width of thegrooves 19, so that when the collar which is being engaged tends to turnin a reverse direction to the rotation of the drive shaft as in thereturn stroke of the clutch, the teeth on the collar will force theshoulder 211 up out of engagement with the same to allow the collar torotate in a reverse direction and prevent the reversing of the shaft 7.

For the purpose of operating the clutch dogs, a shift rod 31 is slidablymounted upon the side of the connecting rod 13, said rod being looselyconnected to the lug 32 on the slide 30 through a slot 83 in the yoke bya bell crank lever 35 which is journaled at 36 between its ends on theside of the yoke.

In operation the rocker arm 11 is oscillated by means of the handle 15,the clutch being reciprocated during said oscillation and the driveshaft T revolved in the direction according to whichever dog is engagedin the clutch. To reverse the motion of the pro` peller the shift rod 34is reversed in position and when it is desired to lock the clutch so asto prevent the rotation of the propeller,

the shift rod 34 is shifted into median position.

In accordance with the patent statutes I have described the principlesof operation of my invention together with the apparatus which I nowconsider to represent the best embodiment thereof but I desire to haveit understood that the construction shown is only illustrative and thatthe invention can be carried out by other means and applied to usesother than those above set forth within the scope of the followingclaim.

I-Iaving described my invention, what I claim as new and desire toprotect by Letters Patent is Iropelling mechanism for a boat,comprising, in combination, a propeller, a shaft in said boat upon theend of which said propeller is mounted, a drive shaft lying parallel toand connected with said propeller shaft to revolve the latter, a clutchyoke slidably mounted upon said propeller shaft and through which saiddrive shaft passes, a clutch in said yoke and threaded into engagementwith said drive shaft to revolve the latter in forward or backwarddirection, means for reciprocating said yoke member longitudinally onsaid drive shaft and means carried by said reciprocating means forreversing said clutch and causing the drive shaft to revolve in reversedirection.

In testimony whereof, I have signed my name to this specificationj inthe presence of two subscribing witnesses.
